Specification of Letters Patent.

Patented Feb. 27, 1912.

Application led August 1, 1905. Serial N o. 272,157.

To all whom t may concern Be it known that I, GEORGE E. LANE, a citizenof the United States, and a resident of Santiago de Cuba, Cuba, haveinvented a new and Improved Marine Signal, of which the following is afull, clear, and exact description.

'Ihe invention relates to signals such as used aboard ship forindicating a ships course, or for preventing such accidents as arelikely to occur from fogs.

The obj ect o-f the invention is to produce a mechanism of simpleconstruction which will operate to give a signal automatically, and themechanism includes an arrangement for enabling it to operate the usualwhistle, the siren or the bell.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and definitely set forth in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of the case containing the signalmechanism; Fig. 2 is a vertical cross section through the case andillustrating the signal mechanism mounted therein; Fig. 3 issubstantially a horizontal cross section taken through the upper portionof the case and representing the mechanism in plan; Fig. 4 is a crosssection taken substantially on the line 4-4 of Fig. 3 and illustrating aportion of t-he mechanism more in detail; Fig. 5 is a vertical sectiontaken in a front and rear direction and showing the upper portion of thecase and mechanism included therein; Fig. 5a is a view similar to Fig. 5but'representing the lower portion of the mechanism and its case; Fig. 6is a cross section through the case containing mechanism for operating ajangle bell and showing the bell adjacent thereto; Fig. 7 is a planshowing a shoe which is useful in shifting the mechanism so as tooperate either the siren or the ordinary whistle; and Fig. 8 is a viewshowing the extremity of a lever which aords means for actuating thesignal, and this view shows also a portion of the disk which actuatesthe lever.

Referring more particularly to the parts, 1 represents a case havingsubstantially the form of a box elongated vertically and formed aboveinto a rounded dome 2. Within the interior of this case I provide a mainframe-plate 3 of substantially rectangular form, which is rigidlysupported in a vertical position by means of studs 4 which projectinwardly from the rear wall 5. I provide a main shaft or arbor 6 whichis disposed in a horizontal position, being rotatably mounted betweenthe frame-plate 3 and the forward wall 7 of the case. (See Fig. 5.)Adjacent to the frame-plate 3 this shaft 6 carries rigidly a pluralityof signal disks 8, the construction and operation of which will be morefully described hereinafter.

Arrangement is made for driving the shaft 6 so as to rotate the signaldisks 8 continuously when the signal is in operation. For this purpose,upon the forward wall 7 at a suitable point and on the inner facethereof, a dished bracket 9 Fig. 5a is attached, the same havingsubstantially the form of a shallow cup with a flange 10 which isattached rigidly to the inner face of the wall as shown. In the wall 11of this cup a motor shaft 12 is rotatably mounted, the rear extremity ofsaid shaft being rotatably mounted in the rear wall 5 of the case; thisshaft is in a horizontal position. Surrounding the shaft 12 near thebracket 9 I provide a spring barrel 13 and in which there is arranged acoil spring 14 similar to the main spring of a chronometer or clock.Upon the motor shaft 12 adjacent to the spring barrel, there is attacheda gear wheel 15 which is adapted to be impelled to rotate by the spring14 when the same is wound up. This gear wheel 15 meshes with anothergear wheel 16 which is carried by a countershaft 17 disposed between theshaft 12 and the shaft 6.l This gear wheel 16 meshes with a gear wheel18 which is rigidly carried upon the shaft 6, and in this way therotation of the gear wheel 15 is transmitted to the disks 8. In order toenable these disks 8 to rotate at a uniform velccity, I provide anescapement mechanism 19.

Referring now especially to Figs. 3 and 4, I provide an escapement wheel20 which is rigidly attached to the shaft 6, .and with this escapementwheel coperates a verge 21, the said verge being actuated by a balancewheel 22 having a suitable hair spring 23. The arbors 24 and 25 of theverge and balance wheel are preferably mounted between smallframe-plates 26 which are rigidly mounted on the studs 27, projecting infrom the forward wall 7 of the case. lt should be understood from thisarrangement that the escapement mechanism, in connection with the motor,constitutes a clock-work for driving the disks 8 ata uniform speed, suchas that observed in the hands of a clock. The disks 8 are preferablyfive in number. At the left, as viewed in Fig. 5, there are two blankdisks 28; by blank disks I mean that they are simply disks of circularform having plane edges. At the right of these disks 28 there isarranged a disk 29, the function of which is to operate the signal everyhalf-minute for a certain period of time. Beyond the disk 29 there is ablank disk 30, the purpose of which will appear more fully hereinafter,and beyond the disk 30 there is a disk 31, the function of which is togive a signal every half-minute, the said signal being of apredetermined character or code. On the side wall 32 of the case, at apoint opposite to the disks 8, I mount a pair of brackets 33 connectedby a horizontal guide bar 34. Upon this guide bar 34 two signal levers35 and 36 are attached pivotally. These levers extend to a point overthe disks 8 and are provided at their extremities with rollers 37 whichrest upon the edges of these disks, as indicated mostl clearly in Figs.2 and 5; in these figures, the signal levers are represented in a normalinoperative position, resting as they do upon the blank disks 28. Freinthis arrangement, as will appear more fully hereinafter, a rotation ofthe disks 28 will not aect the levers so as to produce a signal.

The disks 29 and 31 referred to above are cam disks, their peripheriesbeing of irregular form so that when they rotate, they could operate todisplace a member resting on their peripheries; this is their functionwith respect to the levers 35 and 36. For this purpose T provide anarrangement for shifting the levers 35 and 36 bodily across the disks.This mechanism comprises a shifting bar 38, which is preferably providedat its middle portion with an offset rest 39, at which point it isprovided together with the rest with upwardly projecting spurs 40between which the levers 35 and 36 rest, as indicated. From thisarrangement it shouldbe understood that if the rack 38 is displacedlongitudinally, it will operate to shift the levers 35 and 36 bodily ina lateral direction. In order to enable the levers to be shifted in thisway from one extreme position to the other, the aforesaid guide bar 34is preferably of substantially the same length as the combined width ofthe disks 8, as illustrated. The rear extremity of the shifting rack 38is guided so as to move horizontally through an opening 41 formed at asuitable point in the aforesaid frame plate 3, and the forward extremityof this shifting rack is slidably mounted in a guide bracket 42 which isattached to the rear face of the forward wall 7 of the case, asindicated most clearly in Fig. 5. As shown also most clearly in thisfigure, the under side of the shifting rack 38 is formed with rack teeth43 which coperate with a seg ment 44. This segment is rigidly carried bya shaft 45 which is disposed horizontally in the upper portion of thecase, having its remote extremity rotatably mounted in the wall 32, asshown most clearly in Fig. 3. Adjacent to the segment 44 a supportingbracket 4G is arranged, which constitutes a bearing for the shaft 45,being attached rigidly to the rear side of the forward wall 7 of thecase. Beyond the bracket 46 a second bevel gear segment 47 is arrangedand this segment meshes with a corresponding segment 48, the saidsegment 48 being rigid with a stub shaft 49 carrying a rigid handle 50,the said handle being disposed on the outer side of the case at theforward side thereof. In this connection, it should be stated that thestub shaft 49 passes through a suitable opening in the wall 7 for thispurpose.

As indicated most clearly in Fig. 1, the handle 50 constitutes a pointerfor a dial 51, the said dial being formed on the forward face of thecase near the dome 2. This dial 51 presents preferably four marks orsymbols, the first bearing the word Off and this position of the handlerenders the mechanism inoperative. Beyond this point the letter /V isplaced and when the handle is in this position the whistle or siren willbe operated automatically. Beyond the W there is a B which indicates theposition for the handle or dial pointer when the bell is to be rung, andbeyond this B there is the word Tow when the dial or handle 50 isopposite the word Tow the mechanism will operate to give automaticallythe signal which indicates that the ship is towing a second craft.

As stated above, when the handle 50 is in the off position, themechanism is inoperative. This effect is produced by means of a ratchetwheel 52 the teeth of which cooperate with a pawl 53, the said pawlbeing preferably formed integrally upon the aforesaid bevel gear segment48; this mechanism is shown most clearly in Fig. 4, the same being shownin the off position. However, by rotating the handle 50 upwardly, thepawl 53 will be disengaged from the ratchet wheel 52 so that the motorspring 14 will begin to drive the signal disks 8. The character of thesignal which will be given by these disks will, of course, depend uponthe point at which the handle or pointer 50 of the dial is brought torest.

If the pointer-or handle 50 is brought to the position of the letter IVand left in this position, the shifting rack 38 will oper# ate to shiftthe signal levers and 36 through a distance laterally equal to the widthof one of the disks. In this way the lever 36 will be brought over thecam disk 29. The lever 35 will then operate on the right hand blank disk28 and will hence be unaffected by the mechanism.

The cam disk 29 is formed on its periphery with a projection or tooth 54such as that illustrated in Fig. 2, and this tooth presents an inclinedforward face 55 which operates to raise the roller 37 carried by thelever 36, moving the lever up to a slightly elevated position, as willbe readily understood. The character of t-he signal given by this diskmay be anything desired, butl I prefer that the signal shall give aconsix seconds, and that the signal shall be operated every half-minute.If the handle or pointer 50 'is stopped att-he pointmarked B on thedial, the levers 35 and 36 will be shifted through a space equivalent tothe width of two disks, so as to bring the lever 35 over the disk 29.Under these circumstances, the bell will be operated instead of thewhistle. In this connection, it should be stated that a whistle cord 56is provided which is attached to the under side of the lever 36, while abell cord 57 is supplied, the

' same being attached to the under side of the lever 35. The manner inwhich these cords operate their respective devices will be describedmore fully hereinafter. When the lever 35 is resting over the cam disk29, it will be understood that the lever 36 is resting upon the blankdisk 30, so that this latter lever will not be affected by the movementof the mechanism. In this way I am enabled to operate the bell withoutthe whistle, or vice versa. If the handle or pointer is thrown over tot-he position tow which corresponds to the extreme position for thelevers 35 and 36, the lever 36 will then rest upon and be actuated bythe cam disk 31, the lever 35 then running on the blank 30; with thisarrangement, the lever will, of course, be unaected by the movement ofthe mechanism, while the vdisk 31 will actuate the lever 36 so as togive the conventional signal indicating a tow. For this purpose, thedisk 31 will have its periphery provided with suitable teeth 58 whichwill operate to give the usual one-long and two-short blows of thewhistle, and I prefer to arrange the mechanism so that a signal is givenevery half-minute.

In the rear portion of the case 1, behind the frame-plate 3, I provide amechanism which is operated both by hand and automatically. Thismechanism will be deonly upon the whistle or the siren. For thispurpose, a whistle cord 60 runs downwardly therefrom in the case insubstantially t-he same manner as the cords 56 and 57 referred to above.

Referring especially to Fig. 2, the whistle cords 56 and 60 have theirlower extremitiespass around guide pulleys 61 and 62, and these cordsconverge beyond these pulleys and attach to a main whistle cord 63; fromthis arrangement, the whistle cords 56 and 60 constitute branches fromthe main cord, either of which may operate to pull the main cord, aswill be readily understood. This main cord 63 passes downwardly betweenguide pulleys 64 arranged adjacent to each other, as shown, and beneaththis point I provide mechanism for enabling the cord to operate upon theordinary whistle or upon l a siren. For this purpose I provide a rockertinuous sound extending over a period of or rocking-plate 65 which is ofsubstantially rectangular form and pivoted near its lower edge and onits central axis upon a suitable stud 66. The principal portion of thebody of this rocker is cut away by an opening 67 so that it presents atits upper edge a longitudinally disposed guide bar 68. Upon this guidebar there is slidably mounted a ring or collar 69, which collar mayoccupy an extreme position at either end of the rocker, as will bereadily understood. From the lower edge of the rocker 65 at loneextremity thereof, a whistle cord 70 leads to a common whistle (notshown), and at the opposite extremity a siren cord 71 is attached whichleads to the siren (not shown) which the ship is supposed to carry. At asuitable point just above the rocker 65, I provide a pair of transversehorizontal guide bars 72, as indicated most clearly in Fig. 5a. Theseguide bars are arranged parallel and their extremities are securelyattached to the side walls of the case as indicated. Near their middlepoints the guide bars 72 are provided with longitudinally disposed slots73 and these slots afford means for guiding a slidable shoe 74, theconstruction of which is shown very clearly in Fig. 7. This shoecomprises a pair of oppositely disposed end plates 75 between whichpulleys or rollers 76 are rotatably mounted, and on the outer sides ofthe plates 75, gudgeons 77 are arranged, which run in and project beyondthe aforesaid slots 73. One of these gudgeons 77 is engaged by theforked ex tremity of a rocker lever 78, the said lever being rigidlycarried by a shaft or spindle 47 9 which is arranged parallel with thestud or spindle 66, passing, however, through the opening 67 formed inthe rocker 65.

To the outer extremity of the shaft 79 which projects through theforward wall 7 of the case, I attach a handle 80 which enables the lever78 to be shifted from one 65 scribed more fully hereinafter. It operatesside to the other, as desired. Upon the outer face of the case adjacentto the handle 80, a partial dial 81 is formed, having two divisions, oneof which is marked Whistle and the other marked Siren the said markscorresponding to the two extreme positions for the handle, whichpositions correspond, as stated above, to the two extreme positions forthe lever 78; thus, when the lever 78 occupies the position shown, thesignal mechanism will operate the ordinary whistle; if thrown to theopposite position, the mechanism would then operate the siren. This modeof operation is made possible by passing the main whistle cord 68between the guide rollers or pulleys 76 and attaching` the same to thering 69 referred to above. From this arrangement it will be seen thatwhen the shoe 7&1 occupies the position shown in Fig. 2, a pull upon thecord 68 will operate to raise the left extremity of the rockerplate G5,in this way operating the whistle cord 70; in so doing, the siren cord71 will be slackened but the siren will not be affected thereby. `Whenthe lever 78 occupies its other extreme position so as to hold the shoe74 at the opposite ends of the slots 78, a pull upon the main cord G8would operate to raise the right extremity of the rocker 65, which wouldpull upon the siren cord 71 and affect the siren without affecting thewhistle controlled by the cord 70. In this way the rocker plate G5constitutes a switch.

I provide mechanism shown more particularly at the right of Fig. 5 forgiving signals of a kind used for indicating the ships course in orderto prevent danger of collision. This mechanism I will now describe.

Between the rear wall 5 of the case and the main frame-plate 8 in theupper portion of the case, I mount a shaft or spindle 82. Near itsmiddle point, this shaft carries rigidly a ratchet wheel 88 and near itsinner extremity it carries also rigidly a gear wheel 84. This gear wheel84 meshes with a second gear wheel 85 which is carried by a disk shaft8G, the said shaft being rotatably mounted below the shaft 82 asindicated. This shaft- 8G carries rigidly a cam or cam disk 87 whichoperates to give automatic signals in a manner which will be describedmore fully hereinafter. Beyond the cam 87 the shaft 8G carries anescapement wheel 88 which cooperates with other escapement mechanism 89including a balance wheel 90, and a hair spring 91 having the usualverge 92 coperating therewith. To the side wall 98 of the case 1opposite the cam 87, I attach a bracket 94, at which there is pivotallysupported a whistle lever 95 and this lever extends to a point over thecam 87, carrying a roller 95 adapted to cooperate with the said cam, asindicated in Fig. 8. To the under side of this lever' 95, the aforesaidcord 60 attaches, as indicated in Fig. 2.

I provide a main lever 97 Fig. 5 having a forked lower extremitypresenting bars 98, the extremities of said bars being loosely mountedon the shaft 82 lying on the opposite sides of the aforesaid ratchetwheel 88. Between the bars 98 a pawl 99 is pivotally mounted, which pawlcoperates with the teeth of the ratchet wheel, for a purpose which willbe described hereinafter, being maintained in engagement with theseteeth by means of a leaf spring 100, as shown most clearly in Fig. 2.From inspection of this ligure, it will be seen that the pawl 99 iscurved in form, presenting substantially the outline of the rudimentarySf To the main lever 97 a helical spring 101 is attached, as indicatedin Fig. 2, the opposite 'extremity of the spring being anchored on theunder side of the dome 2 near the side wall 32 of the case. This springpreferably is attached to one of the bars or forks 98 of the lever.

Loosely mounted upon the rear extremity of the shaft 82 I provide ahandle 108, which handle has a hub 104 which is loosely mounted in anenlarged opening in the rear wall 5 of the case. Beyond this opening,the hub 104 has rigid therewith an arm 105 which lies adjacent to thehandle 108 but on the inner side of the case, as indicated. At its upperextremity, the arm 105 is formed with a laterally projecting finger ordog 106, and this dog projects across the edge of the main lever 97 insuch a manner as to enable this lever to be operated thereby, as will bereadily understood.

The handle 108 affords means for setting the lever 97 over toward theright for the purpose of effecting the automatic pulling of the whistle.In this connection attention is called to the fact that the teeth of theratchet wheel 88 project at the upper edge of the wheel toward theright. lVhen the handle 108 is moved toward the right the lever 97 movescorrespondingly in the same direction and the pawl 99 slips over theratchet teeth until it reaches a position at the right of the positionwhich it normally occupies. The spring 101 by such a movement as this isplaced in tension and through the medium of the pawl 99 it tends torotate the ratchet wheel 88 and the gear train 84C, 85 so as to drivethe cam 87. The escapement mechanism, however, which is in connectionwith the shaft 86 iniiuences the return movement of the lever so as tomake the same uniform and gradual. In this way the spring 101 is made torotate the cam 87. As this cam rotates its irregular edge 107 operatesto raise the whistle lever 95. Evidently when the lever is raised itoperates to pull the cord 60 which actuates either the whistle or thesiren.

I provide an arrangement for indicating to the operator of the signalhow far he should push the lever 108 so as to obtain one, two'or threeblasts of the whistle. For this purpose to the pawl 99 I attach a bellhammer 10S and this bell hammer is arranged so as to lie adjacent to thesurface of the bell 109, said bell being rigidly attached to the upperportion of thelever 97.

The arrangement is such that when the lever` 97 is being set over asdescribed above, the inclined faces of the teeth of the ratchet wheel 83operate to raise the lower end of the pawl, and as the pawl is thrownback into engagement with the next notch in the wheel by means of itsspring .100, the bell hammer 108 strikes the bell 109 so as to give asingle sound or stroke. There is a definite angular relation existingbetween the ratchet wheel S3 and the cam 87 such that if the lever 97 ismoved over sufficiently to engage the next adjacent tooth, the cam 87will then be advanced suiliciently to produce one blast of the whistle.From this arrangement as the operator moves over the lever the bell 109indicates the point where he should arrest its movement. Thus, twostrokes of the bellV indicate that two blasts will be given upon thereturn. In addition to the arrangement comprising the bell 109 forindicating the point to which the handle 103 should be moved, I alsoprovide indications or marks 110 which are on the forward wall of thecase on its outer side and constitute a continuation of the aforesaiddial 51. From the forward side of the handle 103, a pointer 111 extendsforwardly, the same having a tip 112 which is bent down over the forwardedge of the case so as to coperate with the numerals of the scale ordial 110. If the handle 103 is moved to the right sufliciently to bringthe pointer opposite the mark 2, there will then be two blasts of thewhistle blown as the handle returns, said handle of course beingreturned by the spring 101.

I provide an arrangement whereby the handle 103 may operate to blow thewhistle directly and without drawing the mechanism just described intooperation. For this purpose, I provide a bell crank lever 113 which isloosely mounted on the shaft 82 adjacent to the arm 105. This bell cranklever has an arm which extends upwardly and projects across the side ofthe finger 106 as shown most clearly in Figs. 2 and 5, and it isprovided also with a second arm 114 which extends downwardly incliningto the right as shown in Fig. 2. This arm 114 terminates in a laterallyprojecting finger 115 which projects across the lower edge of thewhistle lever 95. From this arrangement evidently by moving the handle103 toward the left, the linger 106 will displace the bell crank lever113 so as to elevate the nger 115. In this way the lever 95 can beraised when desired and as long as it is held up the whistle will blow.In this way the same handle 103 which sets the automatic mechanism inoperation controls as well the manual pulling of the whistle cord.

lVhile I prefer to use a motor operated by a spring such as the spring14, described above, in practice it may be found advisable to use amotor of another description. In any case the motor would have aconnection with an escapement, or other means for enabling it to run ata uniform rate. When I employ a spring motor I provide an arrangementfor giving an alarm when the same is run down. For this purpose,referring especially to Fig. 2, I provide the spring barrel 13 with anopening 116. 1 Pivotally attached at 117 to the gear wheel 15, I providea short clip or plate 118 which is preferably bent slightly as shown sothat its tip rests against the inner face of the spring barrel. Thisplate is arranged so that when the spring 14 becomes uncoiled it willengage the same and force it outwardly. The movement of this plateaffords means for actuating an alarm bell 120, which is rigidly attachedat a suitable point on the rear face of the gear wheel 15, as indicatedmost clearly in Fig. 3. The connection between the plate 119 and thebell,

includes a cord 121, which leads to the bell for actuating the same aswill be readily understood. The extremity of this cord is attached to apin 122, which projects through a slot 123 which slot is 'formed in thegear 15, as indicated in Fig. 2. From this arrangement when the spring14 is run down the plate 119 will be displaced so as to pull the cord121 and ring the bell.

In order to enable access to be had to the forward extremity of themotor shaft 12 for winding the same, the forward side of the case 1comprises a door 124 which is preferably mounted on hinges 125 enablingthe same to be opened as will be readily understood. This door islocated just at the aforesaid bracket 11.

The bell which is actuated by the cord 57 is illustrated in Fig. 6. Thisbell is intended to give a succession of rapid strokes or jangle whenthe bell cord is released. For this purpose, I provide a case 126 whichis attached at a convenient point. Within this case a clapper 127 ismounted pivotally at 128, said clapper comprising a stem which projectsthrough an opening 129 in the casing and carries a head 130 adapted tostrike a suitably placed bell 131. The clapper 127 is pivoted at or nearits middle point and to its rear extension there is attached acounterweight 132. On opposite sides of the stem of the clapper, leafsprings 133 are arranged, the same being preferably curved and lyingopposite each other in such a way as to operate to return the clapperwhen the clapper strikes them and moves them to one side. The rearextension of the clapper is engaged by a lever 134 which is pivoted tothe case at 135, said lever having an arm which projects out of the caseas indicated, and to this arm the aforesaid bell cord 57 is attached. Aspring 136 is attached to the inner arm of the lever 134 and constrainsits extremity, which is bent as indicated at 137 so that said eX-tremity or tip is constantly held against the clapper. From thisarrangement it the cord 57 be pulled to the right according to Fig. 6and suddenly released the clapper will be made to vibrate back and fortha number of times between the springs 133; being iirst thrown by onespring against the opposite spring and then thrown back by the latter.This is because the spring 136 in consequence of the sudden release otthe cord 57 forces the extremity 137 of the lever 134 against the upperportion of the clapper and the swinging head 130 of the clapper is thushurled toward the left according to Fig. 6 striking one of the springs133. These springs bend and by its re-action throws the clapperviolently against the other spring 133. This vibration of the clappercauses its head 130 to strike against the bell 131 again and again inrapid succession so as to produce a chiming sound.

The mode of operation of the mechanism will now be reviewed: Then thehandle or pointer 50 is occupying the off position as indicated in Fig.1, the automatic mechanism in the forward portion of the case is atrest; and when the handle is in this position the pawl 53 is inengagement with the teeth of the ratchet wheel 52 so as to lock themititor against running down. Immediately upon the removal o1" the pawlwith the rotation of the handle, the motor begins to drive the signaldisks 8. The movement ot the handle will be arrested either at thepoints Eh B or Tow. This 1novement of the handle 50 will operate to movethe shifting bar 38 laterally so as to bring either of the levers 35 or36 into engagement with one of the cam disks. In this way, the cam disk29 may be made to operate either of the levers, and the cam disk 31 mavoperate the lever 36. The character of the movement produced by therotation of these cams has been fully described hereinabove. Theyoperate to pull the cords 56 or 57. The cord 56 may actuate an ordinarysteam whistle or a siren. In Fig. 2, which corre sponds to the relationshown in Fig. 1, when the pointer 80 is thrown toward the left, theordinary whistle will be operated.

When the pointer 80 is thrown to its opposite position, the ring 69 ismoved to the opposite extremity of the rocker 65 by means of the lever78, and the cord 56 will then operate to pull the siren cord 71 insteadof the whistle cord 70. By moving the handle 103 toward the right thespring 101 will be extended and through the medium of t-he pawl 99 thisspring will operate to rotate the ratchet wheel 83, the rotation beingtransmitted down t-o the gears 84 and 85 and to the cam or cam disk 87.In rotating, this disk 87 will operate to raise the whistle lever 95periodically, so as to blow a number` of blasts of the whistle throughthe medium of the whistle cord 60, which connects with the main cord 63,which cord 63 is also actuated by another branch cord 56. As the handle103 is moved over, the pawl 99 strikes t-he plate 109 with its hammer108 so as to indicate the number of blasts of the whistle which willfollow upon the release of the handle. The number of blasts is alsoindicated at the dial 110. If the handle 103 is moved to the leftinstead of to the right it actuates the lever 95 directly through themedium of the bell crank lever 113. By means of t-he alarm bell 120 andthe contacting plate 119, an automatic alarm is given when the spring oithe motor is about run down.

Having thus described my invention, I claim as new and desire to secureby Leti ters Patent,
